Question

calculate the number of images formed by plane mirror kept at an angle of 10 degree to each other

Answer 1

image formed by a mirror kept at an ange of 10 degree=360/angle-1

=360/10-1
=36-1
=35

Answer 2

Given,

Plane mirrors kept at an angle of 10° to each other.

To find,

The number of images formed by the plane mirror.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

If two plane mirrors are inclined at an angle x, then,the number of images formed = (360°/x°) - 1

{Statement-1}

So, according to the question and statement-1;

The number of images formed by the plane mirror

= (360°/x°) - 1

= (360°/10°) - 1

= 36-1 = 35 images

Hence, 35 images are formed by the given set of plane mirrors.
